Free fall of concrete - Concrete pour over a standing water in a caisson
(OP)
Hello all,
Does anyone try pouring an anti-washout concrete (SCC)over a standing water in a caisson? Is this possible?
Also, the dewatering of the caisson is not possible or the rate of water intake is higher than the dewatering rate.
Looking for your thoughts and help.
Thanks.

I agree with miningman & Jayrod12, use a tremmie to place the concrete below the water surface.
As you place the concrete raise the bottom of the tremmie pipe (maybe a canvas tube) as the concrete is placed. Always keep the bottom of the tremmie tube below the top of the new concrete so there is a seal.
Any contractor who wants to bid on the job should be familiar with the concept.

I've done fully submerged coffer dams by tremie method...
Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?
